Internode + Nodephone + Asterisk (+FreePBX?)
by Michael Schams 18 Oct '16

18 Oct '16

Hi there, We are planning to switch from a standard phone line to Nodephone VoIP from Internode. I am very keen to test if Asterisk (maybe in combination with FreePBX) is an option for a small team (one trunk, 6 to 8 endpoints, all with various SIP clients). I successfully set up Asterisk 13 and pjsip and FreePBX 13 on a pretty standard Debian 8 box. I suspect the challenges start when it comes to the VoIP SIP details for the trunk. I came across a few forum posts and discussions about the Internode settings, but I wonder if anyone from the LUV community runs such a setup or has some experience with Asterisk and Internode (especially their Nodephone product)? As I pointed out above, we don't have the line yet, so it's more curiosity than a specific problem I want to solve (yet) :-) Any feedback is welcome. Cheers Michael

https://www.hetzner.de/gb/hosting/produkte_rootserver/px61nvme Hetzner offers servers with 64G of ECC RAM and 2*512G NVMe storage devices for E59 per month. They have an IPv6 /64 and a single IPv4 address (you can rent another 2 for a few Euro per month). https://en.wikipedia.org/wiki/NVM_Express NVMe is SSD storage directly connected to PCIe to avoid the latency of SATA. https://www.hetzner.de/gb/hosting/produkte_rootserver/px61 The same but with 2*4TB SATA disks instead. https://www.linode.com/pricing For cheaper hosting Linode is offering a VM with 1G of RAM and 24G of storage for $US10 per month. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Ubuntu Kernel upgrade on a non-pae processor
by Michele Bert 31 May '16

31 May '16

Hi. I have recently installed the latest Lubuntu on a non-pae intel processor, passing the option "forcepae" to the kernel at installation time. The installation completed succesfully, and automatically managed to configure grub to pass such option at the boot time. Now I have a new kernel to install, but if I run: apt-get dist-upgrade The installation (pre- or post-, I do not know) script gives an error notifying that the processor is non-pae, interrupting the upgrade. Moreover now I have an inconsistent installation state, since the generic linux-generic meta-package is installed, but the actual linux-image-4.4.0xxxx, which is a dependency for the former, is not. The ps works normally, but I can not install anything, neither upgrade any other ackage. Any hint? By the way do anyone have suggestion about a nice distribution I could install on that laptop? -- Mick

hardware library
by Russell Coker 27 May '16

I've just started using BOINC and will try using video cards soon. Donations of old PCIe video cards to the hardware library will be good, especially if other people also start using BOINC. I'll probably give a talk about BOINC at a future LUV meeting. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Jabber
by Russell Coker 22 May '16

The Jabber address letmein(a)luv.asn.au will be monitored by multiple committee members. If you have problems finding a meeting or getting in then you can contact that address. An advantage of using Jabber over the mobile phone is that multiple people can use it and that the Jabber "status" can convey useful information. A Jabber status of "sorry the guy with the key missed his bus, will start the meeting 1 hour late" would be better than just wondering what's happening. Please only use that address for problems getting to meetings. The Jabber address president(a)luv.asn.au will be used for official presidential duties. Please don't use it for anything for which email will do. Currently we are having problems finding speakers for future meetings. If you find someone who's capable of giving a good lecture and interested in doing so then please Jabber the president if an immediate contact will help lock it in. https://play.google.com/store/apps/details?id=com.xabber.android https://f-droid.org/repository/browse/?fdfilter=xabber I use Xabber on my phone to read Jabber messages, Xabber is in the Play Store and the F-Droid free repository. F-Droid allows you to download the source and install any version you like. There are many free Jabber servers out there, a Google search will turn up lists of them. It's easy to run Prosody (at the bottom of this message is a quick summary of config file changes necessary). Also we can offer @luv.asn.au accounts to LUV members, but note that account names like "root" will not be provided and accounts will be cancelled for misuse. To setup Prosody first put your address in admins section in /etc/prosody/prosody.cfg.lua: admins = { "sysadmin(a)example.com" } Get a certificate with Letsencrypt and set it like the following: ssl = { key = "/etc/letsencrypt/live/www.example.com/privkey.pem"; certificate = "/etc/letsencrypt/live/www.example.com/fullchain.pem"; } Set a VirtualHost then restart the server: VirtualHost "example.com" Add DNS entries like the following: _xmpp-server._tcp IN SRV 0 5 5269 jabber.example.com. _xmpp-client._tcp IN SRV 0 5 5222 jabber.example.com. Add accounts with "prosodyctl adduser USER(a)example.com" -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Who owns Android ?
by Rohan McLeod 17 May '16

17 May '16

Gathered illuminati; seems to be a curious silence on the question who 'owns' Android; at the heart of an $A8billion dispute between Oracle and Google; which has re-surfaced this week -To what extent can open source software be 'owned' ? -To what extent can a particular distribution of a piece of open-source software be 'owned' ? -To what extent can API's be 'owned' ? regards Rohan McLeod

initramfs and USB sticks that won't boot
by Allan Duncan 09 May '16

09 May '16

I have a number of bootable USB sticks, all 32 bit. These work fine on all my boxes, and work quite well with the one box that will actually _boot_ USB3. I would like to do a 64 bit variant of this and just tweaked an existing system to fit onto a 16 G USB stick. This starts off booting and then times out because it can't find the root device. Delving around in the minimalist emergency environment shows that the USB device is indeed not present - blkid shows all the other devices. The normal boot uses UUID identifiers and non-EFI. The kernel in the initramfs has all the USB drivers builtin. Btw - is there an easy way to unpick initramfs - I found I needed to lop off the uncompressed leading cpio to get at the gzipped cpio filesystem that followed? Any suggestions? Please.
